Thank you.

void CMyDlg::ResetListControl() {
m_ListControl.DeleteAllItems();
int iNbrOfColumns;
CHeaderCtrl* pHeader = (CHeaderCtrl*)m_ListControl.GetDlgItem(0);
if (pHeader) {
iNbrOfColumns = pHeader->GetItemCount();
}
for (int i = iNbrOfColumns; i >= 0; i--) {
m_ListControl.DeleteColumn(i);
}
}

I particularly don't understand this line :

CHeaderCtrl* pHeader = (CHeaderCtrl*)m_ListControl.GetDlgItem(0);

Could you please explain this line of code. Thanks :)

I think that line should be:

CHeaderCtrl* pHeader = m_ListControl.GetHeaderCtrl();

See here[^]. However, that line retrieve first control item from m_ListCtrl object ... does working that line ? I didn't met such approach ...
